在 Linux 上的 ASP.NET Core MVC 项目中构建身份脚手架后运行项目时出现问题

Question

我试过添加

<PackageReference Include="Microsoft.AspNetCore.Razor.Runtime" Version="2.2.0" />

但是 2.2.0 是目前可用的最新版本，与错误不符。重建应用程序后错误仍然相同。

项目.csproj：

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RuntimeIdentifier>linux-x64</RuntimeIdentifier>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.1.1" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.1" />

    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="3.1.1">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>

    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.1" />

    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="3.1.1">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>

    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.1.0" />

    <PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="3.1.0" />
  </ItemGroup>
</Project>

完整错误：

Startup.cs 的第 36 行：

services.AddDefaultIdentity<IdentityUser>()
    .AddEntityFrameworkStores<AppDbContext>();

解决了！我按照以下顺序分别卸载了 dotnet 包：dotnet-sdk-bin (AUR) dotnet-runtime-bin (AUR) dotnet-host-bin (AUR)

然后我以相反的顺序构建了这些相同的包。现在它们都在 3.1.1.sdk101-2 到今天，我的项目再次运行。

Answer 1

我注意到了同样的事情，请查看框架的 ms 更新，几天前有一个更新，预计已安装较新的 nuget 软件包。

您遇到的问题是 nuget 软件包与您的 SDk 不匹配，至少我是这样。在进行 Windows 更新并安装新的 Core Runtime 后，Version=3.1.1.0 一切正常

Answer 2

我通过重新安装解决了这个问题：.Net Core SDK 3.1.101 和 ASP.NET Core Runtime 3.1.1
